Remedy
Check parameter set of the drive by means
of the parameterisation software (, 931E
Software Manual).

l
Effect resolver adjustment. (, 931E
Software Manual)
l Check set motor data. (, 931E
Software Manual)
l
Optimise controller setting. (, 931E
Software Manual)
l
Adjust travel profile (e. g. adjust
acceleration ramps).
l
Reduce load torque of the motor.
l
Optimise controller setting to improve
the running precision. (, 931E
Software Manual)
l
Adjust travel pofile (e. g. reduce
acceleration and braking ramps.
(, 931E Software Manual)
l Amplify following error
window/increase switch−in delay.

l
Check correct fit of the resolver plug.
l
Check resolver cable with regard to
cable breakage, short circuit.
l Check PIN assignment of the resolver
cable plug.
l
Parameterise encoder correctly.
(, 931E Software Manual)
l
Check whether power supply unit
operates correctly, and whether the
supply voltage of the power unit is
settled in the permissible range
(19.2 V DC ... 57.6 V DC).
l Decrease the steepness of the braking
ramp. (^ 931E Software Manual)
l
Connect external brake resistor to X2.
l
Check whether other drives connected
to the DC supply of the power unit have
caused this overvoltage.
